Abstract

The invention relates to a new type of punching machine, which includes a frame, a driving device, a crankshaft, a first crankshaft connecting rod, a second crankshaft connecting rod, a first horizontal guide block, a second horizontal guide block, a first connecting rod, a second Transfer link, the first vertical guide link, the second vertical guide link, the first lever, the second lever, the first mold adjusting connecting plate, the second adjusting mold connecting plate, the first slider connecting rod, the second Slider connecting rod, slider and worktable, the driving device drives and connects the crankshaft, and the crankshaft drives and connects the first crankshaft connecting rod and the second crankshaft respectively, and the slider is located at the working table. Above the table; the new punching machine has simple structure, small inertia, high precision, long dwell time at the bottom dead center, smooth stamping surface of the stamped workpiece, improves the quality of the stamped workpiece, receives small reverse impact force, and has little wear on the equipment. The service life of the equipment is extended.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a novel punching machine. Background technique [0002] A punch press is a device used to stamp sheets. Existing punch presses include the following three categories: 1. crankshaft punch presses; 2. toggle punch presses; 3. multi-link punch presses. [0003] The crankshaft punch is easy to manufacture and low in cost. During the high-speed stamping process, the stamping die has a large inertia, the depth of stamping will change with the speed, and the precision is not easy to control. The time from the time of the workpiece to the stamping of the die to the set depth of the workpiece or the time from the point where the stamping force occurs to the end point of stamping) is short, resulting in poor metal fluidity of the workpiece to be processed, and it is easy to make the stamping surface rough. The quality of the stamping parts in the stamping process is poor. Th...
